To ell whom it may concern:

Be it {known that I, ANDREAS M. Son

mansion, a citizen ofthe United States, residing at Milwaukee, in the county of M11- vveukce end State of :isconsin, have 1nespeciirlly to that type wherein a horizontelly disposed butler her is elastically mounted upon and in advance of the usual elliptic springs suppciting the tront port of the automobile body.

The object of the invention is to provide a buffer of this type having means for adjustebly connecting it with the front of near whereby it may be used on cars already in use and on those having the supporting springs or frame spaced varying distances sport.

Another object of the invention isto provide a. device of this character which will be simple, strong, durable and inexpensive in construction, efiicient and reliable in opera;- tion, and Well adapted to the purpose for which it is designs hill E il

With the above objects in view, the invention resides in certain novel features of construction, combination and arrangement of ports as will be more fully described and claimed.

In the accompanying drawings: Figure 1 represents s. perspective view of the front portion of the frame of on automobile having this improved bufi'cr applied; Fig. is en enlarged detail plan view with perts broken out; Fig. 3 is e transverse vertical section taken on the line 3 -4.3 of Fig. 2; Fig. 4 an enlarged detail horizontel soo tion taken on the line 4% or Fig. 3; F1 9;. 5

is a transverse section taken on the line 5--li ofFig. 2; and Fig. 6 is n detail perspective view of one of the coupling members.

lln the embodiment illustrated, a bumper or bufierlonr l is shown constructed of en lo iron subzitentinlly U-shepedin cross section end with its ends curved leterelly inwerd in the usual m or. This butter is disposed in front oil t e vehicle so vusuul end hes socnred to the-inner teen of itecross her, lon- Qpco'ificetion of lletters Bsten't.

These members :are here shown composed of two thick plates or bars 4 and 5 for the salts of economy in being obvious that they may be mode in n w if :toirnd desirable. The member 5 entends laterally at its opposite edges beyond the sides of the member are edapted to extend under the head ele' ments 5 of the members 3' whereby seicl coupling members 6 and '2' they be adjusted on said members 3 to bring them nearer together or dispose them farther apart es may be desired.

Set screws 9 extend through the inner wall or cross bar of the members 6 and 7 and are designed to engage the members 3 for locking the coupling members 6 and 'l' in edjusted position. A

The members 6 and 7 each has a hollow boss 10 extending laterally outwerd from its well or cross bar and in which is secured a louder rod 11. Around this rod 11 is e coil louder spring 12 inclosecl in a casing 13. The sup porting rod 11 has n sliding engagement ct its free end with s sleeve or tubule-r guide end supporting member 1st of e buffer sup porting bracket 15 which forms port of the ihstening for securing the but? her the cor. rod 11 extends entirely through this sleeve 14L- end is held in operetive en gegement therewith by e. cotter pin ll" or similer. fastening crrenged through the inner end of the red as shown in l and which permits seid rod to move reor- Werd but limits its forward movement.

formed by the end of the boss 10. This spring yieldingly projects and holds the rod 11 and the bumper bar 1 in a projected position and absorbs all shocks which are produced when the buffer bar 1 is brought into forcible engagement with an obstruction. The fastening for securing this buffer bar to the elliptical springs of a car may be of any suitable or desired construction and in the form shown, is similar to that described and shown in my Patent 1,088,471 dated February 24, 1914: and as it forms no part of this invention, it is not thought necessary to describe it in detail herein.

From the above description, it will be obvious that the buffer bar 1 may be adjusted to fit cars, the side bars of the frames of which are differently spaced and that the peculiar form of bar protects the coupling members thereof and avoids all danger of breakage of these parts lelelm as In Invention:

An automobile bufi'er bar composed of an angle iron substantially U-shaped in cross section with the flanges thereof extending inwardly, longitudinally spaced coupling elements mounted therein and having undercut sides, cush- -1omng means for connecting said bar with an automobile frame, and having coupling her, and set screws for'leeking irons substantially U-shaped in cross section, their flanges extending outwardly and with mturned flanges at the free edges thereof for sliding engagement beneath the heads of the'cenpling elements within the and coopere l i a me e emell Q ll ll l In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
